Also, several sizes of the metal sides had to be used where the variation in the size of the box was great' Now, according to the present invention, I eliminate the disadvantages;heretofore encountered, and provide forms which may be adjusted to accommodate any size box with which the machine is to be used. My improved form, as shownin Fig. '2, consists of two parts 8, 8. Each of these parts or sections comprises a longitudinally extensible side wall 9, and longitudinally variable end extensions 10. The side bars, as

best shown in Figs. 3 311114;, are made up of a plurality of sets of'strips 11 which inter-fit and may slide toward or away from each other, this sliding movementbeing brought about by racks 12 which "engage a pinion 13 that is faston a Sl1a ft"14:,

rotatably mountedona frame-or rigid support engaging member 15. This frame has a plurality of slide ways on tracks 16, and the strips 11 have grooves 17to...perm it the strips to slide on the frame;

Each frame has a socketor tube 18Itofie: ceive one of the pins. 6 of the cross" arm of themachine, and screws 19 'are'employed for clamping the frame to one of the pins. The back of the socket has an aperture20 to allow the insertion of a screw-driver for turning the grooved head-"21 of the shaft .14, and it will be obvious'that whenfthe shaft is turned, the pinion will cause. one set of the strips 11 to move inone direction, and the opposite side to move in theopposite direction. To permit this, each set of strips is rigidly connected to a corner member 22. c f

' Each corner member is also rigidly connectedto fixed fingers 23 (Fig. 5) ,forming the stationary portion of one of theend extensions 10, and'it will be noted from Fig. 2 that the fingers at one end of the form sectionare of greater length than the fingers', at the other end of the; form section, so

that the fingers at the opposite endoverlap or break joints, so location. 7

Each set of the fingers 28 cooperates with a set of adjustable fingers 245, that have tongues 25 at their sideslsliding grooves as to stagger the gap I 26 in thesides of the fingers 23.

A ,A tie bar 27, which is movable along the stationary v fingers, is rigidly connected by screws 28 to the movable "fingers 24, and acts asan operating member to cause. all of the fingers of the set to movefin unison.

ffA screw29 engagsia threaded aperture i in the intermediate por'tionof the tie bar,

v of the other form section. in contracted position.

In operation, it will be readily understood that when one of the screws 5 of the machine'cross arm is turned, the pins (3 which cooperate w1th said screw Wlll be moved toward or away from each; other, and this will cause theform sections 8 mounted on A those particular pins, to move with the lat ter. When theseform sections, have been 5 is discontinued, and then the operator, by means of a screw-driver, may turn someor all of the screws 29 to adjust the movable fingers 24- to accommodate the adjustment ofthe pins 6. Then, if desired, the operator can also operate the pinions 13' to cause the opposite sets of strips ll of each of the side walls 9 to move toproper position to ac? commodate the particular box that the, form is to support. I ,7 From the foregoing, it is believed that the constructiom operation and advantages of the invention may be readily understood, and it is apparentthat changes may be made in "the details disclose'd, without departing from the spirit of the invention, as 'expressed in theclaims.
